Yes, merino wool is warmer than cotton. Merino wool fibers have a natural crimp that enables them to trap more air and insulate better than cotton. This makes merino wool an ideal choice for colder conditions, providing warmth even when wet, unlike cotton, which loses its insulating properties when damp. Furthermore, merino wool is also breathable, which helps regulate body temperature and reduce sweat build-up.
